PLEASE READ FIRST: this is a solid model of the vive controller NOT INTENDED TO BE USED TO REPLACE THE SHELL OF THE REAL CONTROLLER. it's to scale in millimeters. It's low poly with no manifold edges or any other problems that would make a boolean difficult. as such the size and location of the sensor reflectors are correct but they are not an accurate representation of the sensors. I designed this so I could made custom controller attachments. it has worked well. also note I have not used the top of the controller for any modding yet. I have the screw holes accurate on that part because I thought that might be helpful. but it might cause a boolean issue. The side grip buttons have been extended out so that when this model is subtracted from another. they should sit comfortably in there. realized after completing a print this was not the right scale. not sure how it got incorrect but i suspect some program converted from MM to inches. everything is still to scale. it's just the wrong scale. don't have time to fix right now. just didn't want anyone to fail a print because of my mistake.
